I am just learning to make knives and was given some ATS-34 to play with. I have made a knife out of it, now I need it heat treated. The tool room guys at work said they would do it for me I just got to tell them how. I now it willn't be as good as if I send it off to be done, but this is my first real knife, still learning alot.(I have made some out of files but there all I did was temper it in my oven and left it hard so I did not need to heat treat it)
